def healthCheck(name: String, unhealthyMessage: String = "Health check failed")(checker: HealthCheckMagnet): HealthCheck

Converts a code block to a com.codahale.metrics.health.HealthCheck and registers it.
Converts a code block to a com.codahale.metrics.health.HealthCheck and registers it.
Use it as follows:
```
object Application {
  // The application wide health check registry.
  val healthCheckRegistry = new com.codahale.metrics.health.HealthCheckRegistry()
}
trait Checked extends CheckedBuilder {
  val healthCheckRegistry = Application.healthCheckRegistry
}

class Example(db: Database) extends Checked {
  private[this] val databaseCheck = healthCheck("database") { db.isConnected }
}
```
The code block must have a result of type Boolean, Either, or com.codahale.metrics.health.HealthCheck.Result.
- A check result of true indicates healthy, false indicates unhealthy.
- A check result of type Right[AnyVal] indicates healthy, Left[AnyVal] or Left[Throwable] indicates unhealthy. The embedded value (after applying .toString) or throwable is used as (un)healthy message.
- If the check result is of type Result, the result is passed unchanged.
- In case the code block throws an exception, the result is considered 'unhealthy'.
name
the name of the health check
unhealthyMessage
the unhealthy message for checkers that return false, defaults to "Health check failed"
checker
the code block that does the health check
